Abstract
A fall arrest device (100) for use on an elongate support (180) including locking cams (132, 133, 134, 135) embodied by first and second independent actuable cam elements (133, 135), said cam elements (133, 135) being biased by a bias (132, 133, 134, 135) into locking engagement with the elongate support (180) and being actuated by a common arrester (128) in response to a sudden change in load experienced by the device (100) such that said first cam element (133) traps the elongate support (180) relative to a chassis (102) when the elongate support (180) slopes in a first direction and such that said second cam element (135) traps the elongate support (180) relative to said chassis (102) when the elongate support (180) slopes in a second direction.
